T all whom t may concern: Y

Be it known that ALFRED G. F. lxUnowsur, a citizen of the United States, residing in borough of Brooklyn, city of New York, in the county of Kings and State of New VYork, have invented certain new and useful Improvements 1n Type-Writing Machines,

l of which the following is a specification.

This invention relates to pape;` handling l devices for typewriting machines.

The object ofmy invention is to provide van improved gage against which the upper edge of the paper may' be gagedwhen 1nserted in the machine. l provide improved means-for moving said gage toward and awa-y from the printing line on the platen,

j ing gage, arranged'to slide' upon said sta-v and. for positively locking said gage where adjusted. o

In prior gages, such as disclosed 1n Patent llo. 963,629 of July 5, 1910, the setting of the gagewas effected by loosening screws by meansv of a screw-driver, adjusting the table to which the gage wasfixed, and then tight ening the screws. If a frequent re-setting of the gage was required, the screws'weref,

sometimes only partially tightened, so that the' gage couldbe more readily re-set; but

this made the gage sometimes liable to acci` dental disphxcement. There was4 also rovided a. swivel joint to adjust the lip of the table close to the surface of the platen af- -ter adjusting the table forwardly or b aekwardly. The table was in consequence sometimes susceptible to accidental' displacement by being swung down about said pivot.

The present improvements render the gage more easily adjustable, and liability of acci-v tionary part, whereby said gage is moved toward and. away from thepprinting line on the platen. A rotatable shaft having Aa finf ger-.piece carries pinions which mesh with.

racks fast on each end of said gage, 'so that when said shaft is 'rotated by the operator,A 'the gage is always positively held parallel to the printing line. The gage may be formed as part of a slidable extension of said `table and the racks may be formed on said extension. A thumb-nut is provided which binds said shaft and locks the gage. Thus, the

movement, adjustment, and effective' locking of the paper alining gage, are readily accomplished by merely turning a knob ixed 'on said shaft and tightening said thumb nut.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, vFigure 1 is a general perspective view of the im" prov'ements. Fig. 2 is a sectional view of the platen and the paper gage adapted to it.

Fig. 3 is a longitudinalsection, taken on the A The usual platen 1 1s revolubly mounted by its axle 2 on a platen frame 3. A sloping paper adjusting table 4' is fixed above the platen frame'and facing the operator, about tangentially to the surface ofthe platen, being vfastened to brackets 5 by screws 6; said screws'preferably passing through slotted holes 7 in the table to adord slight 'adjustment between its bent edge or lip 8 and the surface 9 of the platen; such adjustment being permanent, or at' least infreqaiently. made. Said brackets 5- are slid bly splined on rod 10, which is in turn fixed 'rigidly'.fglo

the vplaten frame 3.

On the rear side of the table orv sectioxi is arranged a slidable table o1' section jd, having a bent projection 12 serving as a gage for the top edges of the sheets, and said slidable table is guided by its edges 13 fitting between the edges 14 of the inwardly bent ears 15 of brackets 5. To, keep the surfaces ofsaid tables in contact and prevent rattling, a screw 16 isv passed through a hole 17 in table 4', and through a. transverse slot 18-in table 11, and threaded into a boss or stud 19 at the back of `table 151. A spring member` 20 having arms 21 is interposed becontact between said surfaces is insured, Without offering too great opposition to th adjustment of the upper section 11.

At the rear of the table a horizontal shaft l 22 is rotatably mounted in bearings 23, provided on brackets 5', and preferably passes through a hole 19il intheboss -19 to steady the shaft. Pinions 24 are fixed on shaft 22 to mesh with parallel racks 25 formed at each end of the table 11; so that when shaft 22 is rotated," by turning the knob 2 6 fixed;

y ion 'at each end ofthe shaft 22, both ends of the gage l2 are adjusted simultaneously vso the bracket 5 1s t e gage always moves parallel to the printing line. The gage 12 having been set\ 1t may be locked by tightening a thumb nut on the threaded end 28 of shaft 22; causing the collar 29, fixed on said shaft, to bind against the bearing 23.l r 4 A side gage 30 is provided on table Il. Any suitable means maybe used to adjust the ntire device longitudinally. Eachy bracket 5 may be bent backwardly at 31 and upwardly at 32, to form a yoke having bores 33, whereby the bracket ismounted on the rod 10. In said" yoke -is seated'a spring Bwhich presses a key 35 into a groove 36in said rod, v/vherehy prevented from' turning although the brackets 5 may be shifted along said bar to adjust the table. Notches'are formed on the rod 10 and a" detent 38 is mounted on one of the brackets 5 to'engage said notches. Detent Vd8 isfpivoted on ear 39 of bracket 5, and ,is formed With a fingerpiece 40 to release'the bracket for adjustment. A spring 41 may be provided for the detent. i

When it is desired to gage a succession vof sheets, the first or trial sheet is inserted, and a certain line thereon is brought to register with the printingA lineon the platen; the gage 12 is then adjusted, by` the knob 26, so that wit touches the upper edge ofthe Work sheet. The thumb nut 27 isthen tightened to' lock the gage. gaged by the gage l2 to agree with the trial sheet. One of the features of the improvement provided herein, consisting of a stationary section-fixed close to' the platen and a slidable section which Vcan be extended, is of advantage; since the two sections really con, stitute one table, the length of which. may be varied at Will, so that'the gage v12 may be adjusted to any position While a complete table extends therefrom to the surface ofthe platen. i: J

Variations may be resorted to Within the Y' scope ofthe invention, and portionsof the improvements may be used Without 'ot-hers.
